add a package.json

[arianra]

Please consider adding a package.json to the repo, see: https://docs.npmjs.com/files/package.json

It lets npm identify this repository as a package, allowing us to use npm to manage it as a dependency for our projects.

Please follow Fontship issue №88 and fontsource issue №66 for progress/options on this. All the League fonts will be enabled with whatever solution is arrived at between those two.
